...ia64, and Debian has a longstanding patch that changes the install targets to install static binaries for ia64. This can be generalised to checking whether KLIBCSHAREDFLAGS is defined, as without that we can't expect to build a working shared library. * Include the necessary files in scripts/Kbuild.install so that KLIBCSHAREDFLAGS is defined at install time. * Install static binaries instead of shared if KLIBCSHAREDFLAGS is not defined. * Only install the shared library if KLIBCSHAREDFLAGS is defined. * Only build the shared library and binaries if KLIBCSHAREDFLAGS is defined.

Following patch improves integration with kbuild. With a future kernel (2.6.14-rc) it now has working support for 'make clean'. Included is an example of how to compile an early userspace program. I selected gzip as the most simple one for this - and left out all the links to different names (gunzip etc.) Before proceeding with this I ne...

Hi Peter & others. Here are three patches that does the following: #1 - Update kbuild part of klibc so make clean works Adds gzip including a sample kbuild file #2 - Factor out definition of usr/ to two variables #3 - Move kbuild files to reflect location in the kernel As requested in earlier mail I need a bit of guidiance of what you expect from the kernel integrated parts of...

I'm still pondering with kbuild and klibc. Next in line was to get ipconfig support in the kernel (build wise). A little challenge that is bigger than anticipated was to create a shared executable. This required a far bigger rewrite of Kbuild.klibc than originally planned. The good part is that I now managed to treat linking of...

Signed-off-by: Sam Ravnborg <sam at ravnborg.org> --- This is as more a RFC than a real patch. It changes the kbuild part of klibc to understand subdirectories when building the library. My limited testing so far says that it works and it has solved a few outstanding issues. Now for example touching SYSCALLS.def does indeed cause a rebuild of klibc library _and_ all programs. But it breaks all architectures in t...

To make it more obvious where the files are supposed to end up move files so they reflect the directory structure in the kernel: mkdir scripts mv kernel/Kbuild.* scripts/ mkdir usr mv kernel/Kbuild usr rmdir kernel Furthermore: - updated cp-to-kernel to refelct new directory layout - teach cp-to-kernel to place gzip right under usr/ - Add '#' in front of comment in usr/Kbuild --- I assume cogito will see this as proper renames. The file move was...
